Handling complex data types
When dealing with web services, handling complex types falls into the following categories:
• Mapping the data types of a web service to consume to ColdFusion data types
• Understanding how clients reference your ColdFusion data types when you publish a web service
Consuming web services that use complex data types
The following table shows how WSDL data types are converted to ColdFusion data types:
ColdFusion data type
numeric
Boolean
string
array
numeric
binary
WSDL data type
SOAP-ENC:double
SOAP-ENC:boolean
SOAP-ENC:string
SOAP-ENC:Array
SOAP-ENC:float
xsd:base64Binary
